Periodic Trends

Front

What is the minimum energy required to remove an electron from the ground state of an atom?

Back

Ionization energy is the minimum energy required to remove an electron from the ground state of an atom.

Front

Which periodic group has the smallest atomic radius?

Back

Noble Gases have the smallest atomic radius among the periodic groups.

Front

What term describes an atom's tendency to attract electrons when chemically combined with another element?

Back

Electronegativity is the term used to describe an atom's tendency to attract electrons.

Front

What are the characteristics of Calcium in terms of its metallic properties?

Back

Calcium is a metal, has low electronegativity, and has 2 valence electrons.

Front

Which group of elements includes the most active elements?

Back

The Halogens group includes the most active elements.

Front

Define atomic radius.

Back

Atomic radius is the distance from the nucleus of an atom to the outermost shell of electrons.

Front

What is electron affinity?

Back

Electron affinity is the amount of energy released when an electron is added to a neutral atom.

Front

Explain the trend of electronegativity across a period in the periodic table.

Back

Electronegativity increases across a period from left to right due to increasing nuclear charge.

Front

What is the trend of ionization energy down a group in the periodic table?

Back

Ionization energy decreases down a group due to increased distance of the outer electrons from the nucleus.

Front

What is the significance of valence electrons in chemical bonding?

Back

Valence electrons determine an atom's ability to bond with other atoms and form compounds.
